The enumeration of the 1920 Census occurred not in April as was usual, but upon request by the Dept. of Agriculture it began in Jan. of 1920. The reasoning was the more farmers would be home in January, and questions about their recent harvest would be fresh in their minds. An indication of how the U.S. was still an agricultural nation. Due to the changes in boundaries from the recently ended World War I, respondents were asked to be more specific about what province or city they or their parents were from, if they were born in Austria-Hungary, Germany, Russia, or Turkey. Others just had to name the country. Individuals were enumerated as residents of the place in which they regularly slept, not where they worked or might be visiting. This was because of the large numbers of transients, or "floaters".
